Haagen-Dazs Bananas Foster Ice Cream (2010, 2012): Banana ice cream with a brown sugar-rum-cinnamon swirl, made with real bananas AND real rum. It saw two limited-time runs.
That does look yummy. Entemanns used to sell ice cream sandwiches made with frosted donut-flavored cookies. I discovered them as clearance items after they were discontinued and they were yummy.
